Characterisation of in situ soils based on the resilient soil modulus obtained using Light Weight Deflectometer (LWD)
Abstract The Light Weight Deflectometer (LWD) is a portable device that measures the onsite dynamic or resilient modulus (Evd) of subgrade soils and pavements. The LWD, which has been used extensively in Europe and the United States, has become popular for assessing the stiffness of…
